Question

questions:

1. what is variation, and how does it help species survive when the environment changes?

Explanation:

Variation refers to the differences in traits among individuals within a species. These differences can be genetic (due to mutations, genetic recombination) or environmental. When the environment changes (e.g., climate change, new predators, availability of resources), species with variation have a higher chance of survival. Some individuals may possess traits that are better suited to the new environment. For example, if a food source becomes scarce, individuals with a trait that allows them to access a different food source (due to variation) will survive and reproduce. Over time, this leads to the species adapting to the new environment.

Answer:

Variation is the differences in traits among individuals of a species. It helps species survive environmental changes as some individuals with favorable traits (due to variation) can adapt, survive, and reproduce, passing on those traits to the next generation.
